i tend to ignore free kick SA now and instead pick my player with highest rated shooting skill, too often you get a defender given free kick SA and when you look at his skills it says he cant shoot for toffeee or it isnt even a key skill, not sure there's actually a sure logic tho. i weakened my team against an easy cup oppo at the start of the season and the game picked my keeper to take free kicks coz my set player wasnt playing, he scored from 2 of them and got an assist(i assume from one of them free kicks from out wide), so maybe your keeper taking corners and free kicks is the way forward, lol. talking of corners, i set my best crosser over any of my multiple corner specialists, and seem to score from at least as many. for defending them, a defensive wall SA may help but then a good quality defence might do well enough without a player having that SA anyway
